If you’re running raspiBackup on Arch with ssmtp you might be want to change ssmtp to msmtp.
Since Arch doesn’t support ssmtp anymore (wiki.archlinux.org) it’s a good idea to swap to msmtp.
We did a Pull – Request on GitHub to include msmtp support.
Next released it’ll be included. If you want to swap now you can see the changes here (GitHub).
